Merge branch 'acpi-pm'
* acpi-pm: ACPI / bus: Move duplicate code to a separate new function mfd: Add support for Intel Sunrisepoint LPSS devices dmaengine: add a driver for Intel integrated DMA 64-bit mfd: make mfd_remove_devices() iterate in reverse order driver core: implement device_for_each_child_reverse() klist: implement klist_prev() Driver core: wakeup the parent device before trying probe ACPI / PM: Attach ACPI power domain only once PM / QoS: Make it possible to expose device latency tolerance to userspace ACPI / PM: Update the copyright notice and description of power.c
